i have written code for this but it is deleting after checking the value

  string fileName=@"D:\projectpath\abc.csproj";
     XNamespace ns = "http://schemas.microsoft.com/developer/msbuild/2003";

        XDocument xDoc = XDocument.Load(fileName);

 var b1 = xDoc.Descendants(ns + "Compile")
            .Where(el => el.Attribute("Include").Value == @"Orkut\abc.Designer.cs");
if (b1 != null)
        {
            b1.Remove();

            xDoc.Save(fileName);
        }

Answer 1

Use IEnumerable<T>.Remove() extension to remove every matching node from its parent node:

xDoc.Descendants(ns + "Compile")
    .Where(el => (string)el.Attribute("Include") == @"Orkut\abc.Designer.cs")
    .Remove();

xDoc.Save(fileName);

If you want to delete all Compile elements which has include containing Orkut\\Cart\\Cart.Designer then use following condition to select those elements:

Where(e => e.Attribute("Include").Value.StartsWith(@"Orkut\Cart\Cart.Designer"))
